Dandelion-like SnO2 microspheres on graphene oxide sheets with excellent photocatalytic properties

Influence of interface combination of RGO-photosensitized SnO 2 @RGO core-shell structures on their photocatalytic performance

“…XRD patterns of as-prepared SnO 2 , SG-E and SG-C were displayed in Fig [27,28]. According to Scherrer equation D=kλ/(βcosθ), where D is the crystallize size, k is a dimensionless shape factor (0.89), λ is the X-ray wavelength (0.15406 nm), β is the full width half the maximum intensity in radians and θ is the Bragg angle, the calculated mean crystallize size was 13nm.…”

Highly efficient synthesis of extremely fine nano-SnO2 photocatalytic materials by dealloying Cu50Sn50 alloy powders with mainly exposed {123} facts in η-Cu6Sn5

“…29) (SnO 2 prepared by a melt-spinning and room temperature dealloying method), which once displayed better photocatalytic performance compared with other SnO 2 materials synthesized by spinning–dealloying, 29 commercial SnO 2 , 29 and literature notable SnO 2 -based photocatalysts. 48–50 These results suggest that the milling–dealloying method is a more effective method for fabricating higher activity nano-SnO 2 . Furthermore, it was noteworthy that SnO 2 -300 was superior to SnO 2 -150 (the 1.5 h RhB degradation rates were 90.06% and 86.20% for SnO 2 -300 and SnO 2 -150, respectively).…”
